Lisa Gives Up Control

Author's note: New author! I'm a huge fan of this story by BronzePlaceWriter, all credit to them for their amazing work. I've added in this branch to try some different paths, but still keep it tied into the original story, so some parts will be original, and some parts will be the same. New in this route will be themes of free use, and impregnation.

Diana pulled away from her sister slowly, pulling up her panties, and buttoning her jeans, all the while doing her best to ignore how her legs were still shaking, the after-effects of Lisa's tongue left shivers racing through her body. Blushing furiously, still feeling the eyes of the crowd, she hastily finished dressing, before returning to her seat at the edge of the stage. Frowning in thought.

"Don't write anything", Lisa had gasped, "promise me, please let this happen!"

Diana's hands twitched towards her bag, no one would notice, just a student writing a note, even if they weren't transfixed by the events on stage. Lisa knelt, exposed and alone, legs open slightly, revealing wetness running down her thigh and dripping onto the stage floor. Diana blushed again, as her twin made no attempt to conceal even this from the watching crowd, and then realized what had Lisa so distracted.

Stacy wore Jason's cum across her breasts, who was standing, already dressed, to the side of the stage with a guilty expression. She was having much more trouble with Kyle however, who was clearly upset at being **** to use his friends. Desperately sucking and pulling at his half-softened member, **** to make him cum, in one sudden movement she flipped him onto his back and straddled him. Kyle shouted in surprise, his eyes widening as Stacy filled her pussy with his cock and rode him. The crowd roared, and Diana could see Lisa's lips part in a moan as she watched her friends bucking wildly beside her, Kyle now thrusting to meet Stacy, grunting with each stroke. Surely this had gone too far? With the notebook this could have never happened, would never even be remembered. She imagined herself on stage, watched the **** look in her sister's eyes, and slowly took her hand from her bag, a promise was a promise, and besides, she could always erase this later.

Lisa panted, chest heaving with each shuddering breath, she liked Kyle, more than that, she had touched herself while thinking of him more than once, imagining ways he might pleasure her. She didn't touch herself now, even though her body burned with desire, sweating despite her lack of clothes. Exposed and helpless, watching her crush fucking her friend, had raised her arousal to a level she had never before experienced, a ****, urgent need. Crashing waves of arousal and shame rocked through her body, but masturbating willingly, on stage in front of the entire school was a line she just couldn't bring herself to cross. Soon Kyle began to moan deeply, as Stacy stood on shaking legs, the first shots of cum dripping from her cunt as Kyle rocked with the **** of his climax, shooting more ropes of cum across his chest.

A staff member handed Stacy a piece of cloth.

"Clean him up, you've made a mess"

Legs still shaking Stacy knelt beside Kyle, wiping him down, before quickly wiping herself as well. Lisa felt shame rush back as she realized that the cloth that Stacy was now using to attempt to scrub Kyle's cum from her sex, was once Lisa's shirt. Snapping her legs shut, she was instantly reminded of the hundreds of watching eyes as the main attraction ended.

Unable to meet the other's eyes, Stacy and Lisa knelt side by side, breathing heavily as the crowd whistled and jeered.
